The present invention relates toexhibiti'on and advertisement-standsadapted to be placed at parks, squ fes and the like.

The main o-bject of the invention is to provide a stand substantiallybuilt up of glass and arranged in such a manner that the,

framework carrying the glas fields will'not become visible. A furtherobject is to provide heating devices for the stand which devices duringthe 'Winter prevent accumulation of ice and snow that otherwise woulddisfigure the stand. p p

The invention is by way of example illustrated on the accompanyingdrawings in which: 7 I I p j Fig. 1 is an elevation View, with the lefthalf in section, of a stand embodying the invention. p Y

l/Vhile the invention hereinafter \vill be' de-- scribed and illustratedin connection with an hexagonal stand it should bealnderstood that thecross-section and the shape otherwise of the stand maybe any one withoutdeparting from the scope of the invention.

' Referring to thedrawihg's 1 denotesfthe base of the stand which iswalled and roofed with glass-fields 2 and 3 respectively. Arranged at asomewhat lower levelv than the roof proper are the eaves also composedof glass-fields 4:. All the fields are, as above mentioned, made ofglass and are'retained in their respective positions by means of asuitable framework. Said framework may be built up of bars or the likeof suitable cross-sections such as round metal rods 5 (Fig. havinglongitudinally extending grooves 6 for receiving the edge portions ofthe glass fields. Between the walls of the channels 6 and the fieldsedges is placed an intermediate layer or lining 7 of rubber or the like.'Furtherthe' rods 5 are provided with longitudinal bores 8 for electriccarrent'conductin'g wires. j In order tomake the supporting frameworkinvisible the outer and inner sides the'reof are coveredbyanilluminating device such as shown in Fig.3. The outer and inner sides ofthe rod 5 are'fcovere'd by glass tubes '9 and 10 respectively, ther'ears' of which are shaped to :fit to the periphery of the'r'od. Saidtubes 9 10 may be mercury vapour lamps or the like/thus acting asilluminating means for the stand andcoincidently concealing'theframeworkthereof, In order that the tubes I or lamps even in d'ay-light,When they are extingiiished, shall serve the object aimed at, the outertubes 9 are given an opaque ground or frosted surface in such a mannerthat they will be more or less invisibl from the exte- 'rior of thestand. r Between the roof and the eTaves an'c-lat the base of thestandare arranged pellucid fields 11 and 12 respeetively for placingbills or advertisements thereon. Said fields may be mounted replaceablyin a manner known per se,' either from the outside orthe intenor of thestand. Behind the fields 11, 12

are placed suitable illuminating device's l3 and 14 respectively;wherebyalso these fields are illuminated.

Under the eavesare further placed piellucid fields 15 for bills and alsothese fields are pro vided With illuminating devices at the rearthereof. In order to prevent that the light radiating fromthese fieldsshall interfere with the effect offthe light from the stand proper saidfieldsare pl'a'ced somewhat higher than the lower edge of the eaves andpreferably sloping u wards as illustrated at the left part of Fig. 1.

' To preventaecumulation of ice and snow on the roof surfaces 354suitable heating devices aremou'nted within or under sai'dfie'lds. I I

These heating devices preferablymay consistof resistance wireseinbeddedin channels or grooves 16; in the fields 3-, 4 (Fig. 4) ,whiehWires in the cold season, si'ipplied'with .eleotric current; serve asheaters. Instead of being embedded iii Eliafi'fils', the resistance"wires and in close approximation thereto.

By adapting the colour and lighting of the roofand bill-fields to theremaining light-.

ing of the stand an even effect of light is obtained and no darkportions will appear owing to the framework and the roof.

The electric light for illumination may be switched on and off manually,or automatically by means of a clock-drive, a light sensitive cell orthe like;

One of the fields 2 may be provided at one side thereof with hinges'toserve asa door which gives access to the interior of thestand.

The stand described above is mainly intended to be used for usualexhibition of goods and advertisement thereof, but may also be .used formannequin exhibition. In such case a chamber fonchanging10f costumes maybe arranged below the proper stand, as indicated in Figs. 5 and 6.

1 is the base of the stand and 17 the floor thereof. Below the floor isprovided a chamber 18 having an entrance and exit 19 normally closed bya plate or door 20... Access from the chamber 18 to the stand proper maybe had by means of a staircase or a lift means. An embodiment of such alift arrangement is illustrated in Figs. 5 and 6. The central portion 21of the floor 17 is connectedto a means for lowering the same into thechamber 18 andraising the same to nor- 1 mal position. In Fig.5 the'saidportion 21 is secured to the end of a vertical threaded rod 22 whichmeshes with a rotatable nut 23 adapted to be rotated, but not raised orlowered, either manually or by a suitable motor The central floorportion 21.

(not shown). is guided between guides 24 when raised or lowered. j j

In order to conceal the opening in the floor 17 when the central portion21 is lowered the following arrangement maybe used. In the stand arearranged a set of vertical guiding threads 25 placed near the periphery.ot the said opening.

I At the floor is'p'laced a piece of'suitabl'e cloth 26 to whicharesecured guiding rings or the like'cooperating with the said guidingthreads, and strings by means of which" the cloth may be drawn upwardlyalong the guiding threads toform a curtain whichconceals the opening inthe floor. In

"lowered position,"resting on thefioor 17, the

said clothor curtain will'conceal the joint between the central portion21 and the remainderof the floor 17. The guiding threads and thestringsmay consist of gut or the like, whereby they are practicallyinvisible.

It will beun derstood that'the details of the stand maybe altered inmany ways with out departing from the spirit of the invention, and thespecial embodiment here illuscertained the nature of my said inventionand in what manner the same is to be performed, I declare that what Iclaim is: H

1. An exhibition-stand comprisinga framework forming a housing and aroof and built up of glass panels, a chamber below the housing, a floorseparating the interior of the housing from the chamber, and meanswhereby a portion of the floor is adapted to be low ered into said lowerchamber and again raised 7 to normal position.

ber, adjustable supporting means in the casing'fOr raising and loweringthe disc portion and for holding the same in normal position flushedwith the main part of the floor, and guiding means between the floor andthe bot tom of the chamber for the disc-like portion.

3. An eXhibition-standin accordance with claim 1, wherein verticalguiding threads arearranged in the upper part of the housing andanchored to the floor adjacent the movable portion thereof, and a clothengaged with the guiding threads and serving as a cover to hide themovable portion of the floor. r v 4. AneXhibition-stand in accordancewith claim 1, wherein the framework includes vertically arranged rodsfor accommodating the 'faces of the rods and the tubes on the outersides of the rods having a frosted outer surface, substantially as andfor the purposes set forth. w 1

In testimony whereof'l'atfix my signature.
